Fu Xuechen commanded the craftsmen to pour the molten glass that had been burned in the crucible onto the steel plate, and after a while, clamp it up together with the steel plate, put in the coolant, and the mist was steaming, the formed glass plate and the steel plate were separated, and the steel plate was removed, and the glass plate with irregular edges was left in the sink.

At this moment, the glass plate has not yet been completely hardened, so I took the opportunity to cut it in the water with large scissors and cut it into a rough rectangle, with a slightly unregular edge, which can be inlaid with a wooden frame later.

It doesn't matter, the key is the output, only such an expensive baby crucible can withstand a thousand degrees of high temperature calcination, each time it has to be burned for eight to ten hours, and then cooled out and cleaned up, and re-melted the glass into a liquid, this is another hour. The crucible was not large, and the liquid glass poured out was only enough to make a three-foot square piece of glass, and there were still many small bubbles left in the glass that could not be handled.

Thinking of the novels he had read in his previous life, Fu Xuechen found that it was all nonsense, no wonder there were suspected travelers, and after his death, he was angry and engraved the words ", never come again" on the epitaph.

In this era before the beginning of science, even if glass can barely be made, it is not as cheap as imagined, unless a blast furnace is built in this year, and then the liquid glass can be stirred at a high temperature of 1,000 degrees.

Naturally, Fu Xuechen didn't underestimate the wisdom of the ancients in this era, she didn't think of a solution, it didn't mean that others couldn't do it, she just barely made this small flaw and a lot of glass square plates, and threw the manufacture of glass plates to Xie May.

Xie May participated in the entire manufacturing process of this glass plate, and Fu Xuechen told him all the recipes and areas that needed to be improved, whether he could think of ways to improve the manufacturing process in the future and create perfect glass, then Fu Xuechen didn't care much.

Nowadays, glass is so difficult to make that it is necessary to apply a combination of tin and mercury paint to make a mirror, which can be poisonous, and in the current era when it is completely impossible to prepare light metals such as aluminum, glass mirrors containing mercury are not a good choice.

Fu Xuechen didn't take the glass production seriously at all, but she didn't know that after she left, the entire Xie Clan porcelain kiln was simply fried!

The next day, Xie's porcelain kiln.

Xie May gave an order, and the craftsmen opened the kiln where the glass was burned.

After a long time, the heat has dropped to a level that the human body can tolerate, and even because the climate is still cold, it will be comfortable to be close to the kiln.

From the outside, the crucible containing the raw materials is still complete, this is the strongest and most fire-resistant quartz crucible found in the blacksmith's workshop, which is generally used to calcine hundreds of steel, and is an indispensable tool for forging divine weapons, and the cost is expensive.

When I took out the crucible, it was covered with a layer of white powder, and the upper layer of powder was erased, and what was surprising was that there was a solidified translucent crystal at the bottom, although it seemed to be a little green, and there were some small bubbles of different sizes visible to the naked eye, but it looked very similar to glass.

Almost all the craftsmen of the porcelain kiln know the glaze, but also know that the glaze is difficult to refine, not only the materials required are rare and numerous, the process is also complex, and the conditions are harsh, but also can only refine a small amount, which is a more valuable luxury than porcelain.

Unexpectedly, right under their noses, the Shaodong family would get such a big pot of glass in such a simple way!

Everyone's expressions were sluggish, when could the refining of glass be so simple?!

"This is glass, not glass." Fu Xuechen looked at the expressions of these people, explained, and then ordered to clean the glass of this pot, and then start the fire again, she wanted to melt the glass of this crucible.

Melting quartz sand requires an ultra-high temperature of more than 1,000 degrees, but it only takes 600 degrees to burn glass, and it is very simple for these porcelain kiln craftsmen to build a small kiln that can burn high temperatures.

There is liquid glass, but it is a difficult task to manufacture glass plates, because the temperature of liquid glass is very high, and no slate tile can withstand it, and the liquid glass will be blown up when it is poured, so only steel plates can be used.

I don't know if the steel will be controlled by the imperial court in the future, but at present, Darong has just established the country, and many management systems are not in place, and there are many blacksmiths who can forge a hundred steel knives, and the Xie family also has one, and a three-foot square steel plate has already been laid and sent over, which is not big, barely enough.

Fu Xuechen commanded the craftsmen to pour the molten glass that had been burned in the crucible onto the steel plate, and after a while, clamp it up together with the steel plate, put in the coolant, and the mist was steaming, the formed glass plate and the steel plate were separated, and the steel plate was removed, and the glass plate with irregular edges was left in the sink.
